Gouged cylinder

[John McEwan]

Lost compression on one cylinder in my ‘23 and found a couple of gouges in a cylinder wall where it looks like the pin circlip has come adrift and the pin has moved sideways. It was already bored to 40 thou oversize and I am not confident it will clean up at 80 thou which is the biggest oversize pistons I can get in Australia. Anyone have any experience with resleeving or know of any larger over sized pistons?

A good machine shop can sleeve a cylinder to any bore you want.

In my profession it (outboard motors) it was acceptable to bore one cylinder. Although I could never get behind that.

Sleeve it.....no worries. I would recommend punching all the holes the same size. As a set of pistons will be more affordable that way.

Gee that’s a shame that’s happened John. It was all going pretty well wasn’t it. 😥

Yes it was. I will be pulling off the sump shortly and popping the pistons for a look at the rings. The problem is it wasn’t the cylinder with no compression that has the gouging. I will look into resleeving or finding a donor block. It was last reconditioned in 1991 so about time again I suppose.
